Put the H5P player on a site

@missing-elements/h5p-offline-player is one custom element, <h5p-player>. It plays a .h5p package from a URL or a picked file: the archive is read in place and a Service Worker serves its files to the H5P runtime. Three files matter: the element (h5p-player.js), the worker (h5p-sw.js) and the runtime folder (frame-assets/). Only the worker has to be served from the site's own origin; browsers refuse a cross-origin Service Worker.

1. Pick the setup

Ask, or read from the project, three things: is there a bundler; can a file be placed on the site's own origin; where do the packages come from.
